Raw water quality variations and its effect on the water treatment processes

This research assesses the variation dynamics of contaminant loading in surface water and its effect on treatment. A comparative analysis variations physicochemical parameters raw quality corresponding treated was carried out using descriptive statistics, matrix correlation, PCA multivariate statistical techniques. Monthly Panel/historical data between 2002 2016 from Ghana Water Company Limited (GWCL) treatment works (Adam Clark plant) at Weija plant simulation (Jar test) were employed. The highest variability observed for colour, conductivity, nutrient (COV;>40%), whilst pH, turbidity, alkalinity, temperature had moderate (COV;<15%). Both natural anthropogenic activities have a significant deterioration (p < 0.01) lack, particularly (r = 0.491). Seasonal also affects quality. Consequently, influence cost production portable water. results this should guide Resources Commission remedial measures to be adopted curtail incessant pollution
